Serial N0. 501,560.

To all whom it may concern:

Be it known that we, FOSTER W. BAssETT and WILLIAM A. HUNTER, J r., citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Flushing-Valve Mechanism; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates the construction of an'improved flushing valve mechanism provided with means for utilizing the water pressure for controlling the flushing water.

One of1 the objects of the invention is the production of a flushing valve mechanism provided with means for securing a positive valve action by utilizing the water pressure instead of opposing it.

Another object of the invention is the production of a flushing valve mechanism comprising double valve compartments and a duplex valve united by a lever for controlling said compartments.

Another object of the invention is the production of a iiushing valve mechanism comprisin a main compartment or chamber contro led by a slide valve and a second or auxiliary compartment or chamber controlled by a ball valve having leverage connections with the iirst mentioned valvea-ndarranged to coact therewith.

Another object of the invention is the production of a flushing valve mechanism combining the advantages of the gravity and pressure systems.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

In the accompanyin drawings, Figure 1 is a vertical section o our improved iiushing' valve mechanism showing the separate va ves in a closed position; Fig. 2 is a similar view showing the valves in an open position; Fig. 3 is a horizontal section taken on line 3-3 of Fig. 1J

Corresponding and'similar parts are indicated .in all the viewsofthe drawings and in the-following description by similar reference characters.

In the drawings the numeral 1 designates a pressure tank which is connected to an angularly formed conduit 2 by a union 3. The conduit 2 extends in a vertical plane from the tank 1 with which it communicates by a passage way 4 and is bent at right angles to itself at 5 and again bent at right angles to itself downwardly at 6 and communicates at its lower end 7 with a flushing pipe.

The angularly formed conduit 2 is formed with ports 8 and 9, which connect the chamber 10 of said conduit with the chamber 11 communicating with the tank 1. The 8 and 9 are arranged to be normally c osed by a vertical slide valve 12, which is formed with a depending stem 13, which stem engages a guide arm 14 formed on the inner wall of the conduit 2, The slide valve 12 extends upwardly in the conduit 2 so that the upper portion of said valve normally closes the upper end of the ports 8 and 9 and is connected at its lower end by the stem 1B to a lever 15 which is pivoted t0 the walls of said conduit and extends longitudinally within the horizontal section thereof.

The slide valve 12 is formed with transverse ports 16 and 17; and said valve is preferably formed hollow and the ports 16 are positioned or formed in the lower part of the valve 12 and the ports 17 are formed in the upper part of said valve. The p orts 17 are normally closed by an auxiliary valve 18 which slidably extends downwardly through the valve 12 in which it is guided by a spider 19. The lever 15 connects with a gravity ball valve 20 which is normally seated in the valve seat 21 formed in the lower end of the conduit 2 and directly above the opening 7.

The conduit 2 is provided with a threeway valve 22 which is formed with an operating handle 23 and said valve is arranged to close a port 24E communicating with chamber 10 and a second port 25 communicating with the flushing pipe. A supply pi e 26 communicates w1th the casing 27 o the. three-way valve 22 and normall exerts pressure in chamber 10. When t e three-way valve 22 is in the position indicated in Fig. 1, valve 20 will be held to its seat and valve l2 will be held upwardly across the portsl 8 and 9. When the slide'valve 22 is'turned to the position .indicated in Fig. 2 the pressure in chamber. 10 -will be reduced and water will flow from said chamber by ports orts "24 and 25 to the flushing pipe by opening 7. I

This discharge of the Water from chamber 1.0 will relieve the pressure in said chamber and permit the pressure in tank 1 to operate the valves 12 and 20 and thereby open ports 8 and 9. When ports 8 and 9 are thus opened, the Water in tank 1 Will flow through opening 4- into chamber 11, pass through ports 8 and 9 into the chamber 10, cross to valve seat 21 and empty by means of openings 7 into the flushing pipe.

The slide valve 23 is arranged to be con` trolled by a spring 28 or an equivalent arrangement, and the valve 20 Will be held away from the seat so long as the pressure of the Water in chamber 11 and tank 1 eX- ceeds the Weight of said valve and, when the Weight of the valve 20 more than balances the Weight of the Water in chamber 11 and tank 1, it will fall to its seat 21. When the valve 2O falls to its' seat, the Water from the supply pipe 26 Will pass upwardly through y port 211 into chamber 10, fill said chamber and pass through ports 16 and 17 into the slide'valve 12 and fill the chamber 11 and the tank-1, thereby lifting valve 18 from its seat on the upper part of valve 12.

It Will be seen that the pressure in Ithe chambers 10 and '1l and tank 1 Will cooperate With the valve 12 and valve 20 so that the flushing power of the Water is not decreased by the operation of Said valves. The tank 1may be a pressure tank formed with a. Cover or be an open tank of the conventional kind. It Will also be seen that the filling of the chambers 10 and 11 and the tank' 1 does not tend to lift the valve 20 from its seat or to detrimentally affect the operation of slide valve 12 with the result that the pressure of the llng water will have the opposite effect it usually has on the closin of the controlling valve.

From tie foregoing description taken in connection With the accompnyin drawings, the construction and operation o'tl-einvention will be readily understood Without requiring a more extended explanation.

lVarious changes in the form, proportion and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of theinvention, as defined in the appended claims.
